Treating outside dimensions as usable fill dimensions
Packaging format
Lay-Flat / 3-Side-Seal Pouches
Lay-flat and 3-side-seal pouches use material efficiently and can be tailored for one-time use, resealability, hanging display, or high-barrier protection. Seal geometry and opening experience should be considered alongside the product and filling process.
PROJECT FOCUSSmall formats leave little room for sizing or seal errors.
A compact flat pouch can work well for jerky, samples, single-use products, refills, and other space-conscious applications.
What the specification must resolve
What to confirm before production.
In a lay-flat pouch, finished dimensions, seal widths, tear location and fill area are closely connected. A compact package can perform well when opening, dosing, filling and burst requirements are resolved before finalizing the dieline.
Key considerations
- Seal widths and usable fill area
- Manual, semi-automatic or automated filling
- Easy-open, resealable or tamper-evident features
- Puncture and flex-crack resistance
Common applications
- Samples and trial sizes
- Jerky and confections
- Nutraceuticals
- Refills and accessories
Where projects go off track

A common question
What is the difference between a lay-flat and a 3-side-seal pouch?
The terms often overlap. A 3-side-seal pouch is typically sealed on three sides and filled through the fourth. Confirm the final construction, seal geometry and filling method with the packer.
